FROM WIKIPEDIA:
Pot metal, also known as monkey metal, white metal or die-cast zinc, is a slang term that refers to alloys that consist of inexpensive, low-melting point metals used to make fast, inexpensive castings.
There is no scientific metallurgical standard for pot metal; common metals in pot metal include zinc, lead, copper, tin, magnesium, aluminium, iron, and cadmium. The primary advantage of pot metal is that it is quick and easy to cast. Due to its low melting temperature no sophisticated foundry equipment is needed and specialized molds are not necessary. It is sometimes used to experiment with molds and ideas before using metals of higher quality. Examples of items created from pot metal include toys, furniture fittings, tool parts, electronics components, and automotive parts.
